Bird Blues progression

The Blues for Alice changes, Bird changes, Bird Blues, or New York Blues changes, is a chord progression. It is named after Charlie Parker ("Bird"). Bird changes are a type of twelve-bar blues.

The progression uses many ii–V or secondary ii–V progressions. This progression has been used in many songs. It has been used in Parker's "Blues for Alice". Toots Thielemans's "Bluesette",[1] Freight Trane written by pianist Tommy Flanagan, and Parker's "Confirmation".[2] also have similar progressions.

Structure

This is a normal twelve bar blues progression. It is in the key of C.

{ \new ChordNames \with { \override BarLine #'bar-extent = #'(-2 . 2) \consists "Bar_engraver" } \chordmode { \override Score.BarNumber.break-visibility = ##(#f #f #f) \set Score.tempoHideNote = ##t \tempo 1 = 60 c1:7 | c:7 | c:7 | c:7 | \break f:7 | f:7 | c:7 | c:7 | \break g:7 | f:7 | c:7 | c:7 \bar "||" } }

A blues progression in jazz looks like this. It is written in they key of C.[3]

{ \new ChordNames \with { \override BarLine #'bar-extent = #'(-2 . 2) \consists "Bar_engraver" } \chordmode { \override Score.BarNumber.break-visibility = ##(#f #f #f) \set Score.tempoHideNote = ##t \tempo 1 = 60 c1:7 | f:7 | c:7 | c:7 | \break f:7 | f:7 | c:7 | e2:m7 a:7 | \break d1:m7 | g:7 | c2:7 a:7 | d:m7 g:7 \bar "||" } }

The Bird Blues progression, in C, looks like this:[4]

{ \new ChordNames \with { \override BarLine #'bar-extent = #'(-2 . 2) \consists "Bar_engraver" } \chordmode { \override Score.BarNumber.break-visibility = ##(#f #f #f) \set Score.tempoHideNote = ##t \tempo 2 = 60 c1:maj7 | b2:m7.5- e:7 | a:m7 d:7 | g:m7 c:7 | \break f1:7 | f2:m7 bes:7 | e:m7 a:7 | es2:m7 aes:7 | \break d1:m7 | g:7 | c2:maj7 a:7 | d:m7 g:7 \bar "||" } }

Using roman numeral analysis, it looks like this:

IM7 viiø7   III7 vi7    II7 v7     I7
IV7 iv7    ♭VII7 iii7    VI7 ♭iii7  ♭VI7
ii7 V7 IM7   VI7 ii7     V7

This chord progression uses many ii–V progressions to the IV chord in the fifth measure. It then uses three tritone substitutions of dominant chords. This leads to the V chord (G7 in C) using half-steps.[4]

C: Am: G(m): F:
IM7 iiø7     V7 ii7      V7 ii7      V7
F: E♭: D: D♭(m):
I7 subii7 subV7 subii7 subV7 subii7 subV7
C:
